Cl 原子得到一个电子变成了Cl-(chloride anion) 二者之间的electrostatic attraction force(静电吸引力)就被称为ionic bond(离子键)。 一个cation吸引一个anion,然后正负电荷相抵消,就形成了NaCl这个ionic compound。 ionic bonding(离子键)对应的化合...
In a molecular compound, such as, for example, water, H2O, or ethanol, C2H5OH, each unit of the substance, the molecule, consists of the number of atoms shown in the formula. In an ionic compound, such as common salt, NaCl, or magnesia MgO, the formula tells us the correct ratio ...

A common example of an ionic compound is common salt or NaCl, in which the sodium atom gains one pair of electrons from the chlorine atom, and forms an ionic bond. Other compounds like NaBr (sodium bromide), KCl (potassium chloride), and CaCl2(calcium chloride) are also ionic compounds. ...
The results implied that the incorporation of metal center into ILs has a great effect on NH3 absorption. Among the investigated MILs, bis(1-butyl-3methyl imidazolium) copper tetrachloride salt ([Bmim](2)[CuCl4]) and bis(1-butyl-3-methyl imidazolium) stannum tetrachloride salt ([Bmim](2)[...

Sodium and chlorine Which one is the cation, or the metal? Sodium That leaves the chlorine for the anion or nonmetal. So, let’s follow the rules to name this: 1. Sodium stays the same 2. Chlor-ine becomes chlor-ide So, what’s the name of this compound? Sodium chloride Try these...
— iodine trichloride Please note that ionic compounds (Type I & II binary compound names) never use prefixes to specify how many times an element is present. Prefixes are only used for covalent compounds formed from non-metal elements. ...
